Popis Long QT syndrome (LQTS) is a hereditary arrhythmic syndrome characterized by abnormal prolongation of QT interval, increased risk of ventricular arrhythmias, and sudden death. It is the most often diagnosed hereditary arrhythmic disorder with prevalence 1:2000. The KCNQ1 gene is one of the 3 major genes (KCNQ1, KCNH2 and SCN5A) which account for 75 % of the genetically identified LQTS cases. The same KCNQ1 mutation c.926C>T (p.T309I) was identified in 10 putatively unrelated families.
